Understand Evidence Gathering via Sniffing in this aerticle a computer connected to the LAN has two addresses. One is that the MAC address that specifically identifies each node within the network and is stored on the network card itself. The ethernet protocol uses the MAC address while building “frames” to exchange the info among the systems. the opposite is that the IP address employed by the applications. The data-link layer uses an ethernet header with …
